Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules.
The problem portion of the rule is as follows of the java step within DisplayHarnessWithClass :

int delimIndex = activityParam.indexOf(":");
if(delimIndex < activityParam.length()-1){
String key = activityParam.substring(0, delimIndex);

In the case where .indexOf(":") fails to find a colon in the string, it will return -1. The step immediately after will then always trigger, since -1 will be less, and the substring action will pull from 0 to -1 resulting in an exception in the logs.

Resolution

This issue is resolved in Maintenance Level (ML) release PRPC 7.1 ML7
